Authentication: X-Subscription-Token: <API_KEY> header

Parameters

|--|--|--|--|--|

| q | string | Yes | — | Query to spell check (1-400 chars, max 50 words) |

Response Fields

| Field | Type | Description |

|--|--|--|

| type | string | Always "spellcheck" |

| query.original | string | The input query as submitted |

| results | array | Spell-corrected suggestions. May be empty when no correction is found |

| results[].query | string | A corrected version of the query |

Example Response

{
  "type": "spellcheck",
  "query": {
    "original": "artifical inteligence"
  },
  "results": [
    {
      "query": "artificial intelligence"
    }
  ]
}

Use Cases

Pre-search query cleanup: Check spelling before deciding which search endpoint to call
"Did you mean?" UI: Show users a corrected suggestion before running the search
Batch query normalization: Clean up user inputs in bulk

Notes

Built-in alternative: Web Search and LLM Context have spellcheck=true by default — use this standalone endpoint only when you need the correction before searching
Context-aware: Corrections consider the full query context, not just individual words
